The present invention will be further described with reference to the accompanying drawings and specific examples, which should not be construed as limiting the invention.

Example 1

As shown in fig. 1-5, the utility model provides an electric fire automatic alarm device, including rectangle box 1, rectangle box 1 one side is equipped with the opening, and the upper and lower both sides in rectangle box 1 all are equipped with the rotation hole, rotate the dwang 2 of connecting vertical setting between two rotation holes, and dwang 2 outer wall cup joints fixed plectane 21, and plectane 21 can be partly outside rectangle box 1 is stretched out from the opening of rectangle box 1. The outer wall of the circular plate 21 is sleeved with a fixed toothed ring 22, the lower side of the circular plate 21 is fixedly connected with the temperature sensing device 3, the upper side of the circular plate 21 is fixedly connected with the sound generating device 4, and the temperature sensing device 3 and the sound generating device 4 are respectively arranged at two sides of the circular plate 21. The bottom side in the rectangular box 1 is fixedly connected with a motor 5, the main shaft of the motor 5 is fixedly connected with a gear 51, and the gear 51 is meshed with the gear ring 22. The gear 51 is driven by the starting motor 5 to rotate, the gear 51 drives the gear ring 22 to enable the circular plate 21 to rotate by using the rotating rod 2, and when the temperature sensing device 3 rotates out of the rectangular box 1 along with the circular plate 21, the external temperature environment can be monitored. The upper side of the sound generating device 4 is fixedly connected with a first electrifying block 41, the first electrifying block 41 is connected with a power transmission line of the sound generating device 4, the upper side of the inner wall of the rectangular box 1 is fixedly connected with a second electrifying block 11, the second electrifying block 11 is connected with a power supply line of the sound generating device 4, and the first electrifying block 41 and the second electrifying block 11 are arranged correspondingly. When a fire occurs, the external temperature rises sharply, and after the temperature sensing device 3 senses the temperature change, the temperature sensing device 3 drives the circular plate 21 to rotate 180 degrees through the PLC control system driving motor 5, so that the temperature sensing device 3 is rotated into the rectangular box 1, and the sound generating device 4 is rotated out of the rectangular box 1 along with the circular plate 21; when the sound generating device 4 rotates out of the rectangular box 1, the first electrifying block 41 can be in contact with the second electrifying block 11, so that the sound generating device 4 is electrified to give out a warning to remind people to rapidly escape. The temperature sensing device 3 and the sound generating device 4 are both in the prior art, and the specific structure and the connection mode are not described herein again. Two horizontal poles 6 of the equal fixed connection in upper and lower both sides of plectane 21, the common fixed connection cowl 61 of the reverse one end of two horizontal poles 6, every cowl 61 all can paste and rotate between the relative both sides of 1 inner wall of rectangle box. When the temperature sensing device 3 is positioned outside the rectangular box 1, the temperature sensing device 3 is exposed outside, so that the change of the outside temperature can be accurately monitored; when a fire occurs, in the process that the sound generating device 4 rotates out of the rectangular box 1 along with the circular plate 21, the arc-shaped baffle plates 61 on the upper side and the lower side of the circular plate 21 can rotate out of the rectangular box 1 along with the sound generating device 4, the openings of the rectangular box 1 can be shielded by the two arc-shaped baffle plates 61, and the fire is prevented from spreading into the rectangular box 1 and burning out components in the rectangular box 1. All be equipped with a plurality of phonation holes 62 on every cowl 61, can spread the alarm sound that sound generating mechanism 4 sent out through phonation hole 62, avoid reducing the alarm sound that sound generating mechanism 4 sent out because of sheltering from of two cowl 61. After the condition of a fire, temperature-sensing device 3 senses the ambient temperature and becomes low, and temperature-sensing device 3 can drive circular plate 21 and rotate 180 once more by driving motor 5 for sound generating mechanism 4 and two cowl 61 are all turned over into rectangle box 1 in, thereby make temperature-sensing device 3 expose once more in the external world, continue to monitor ambient temperature's change.

Rectangle box 1 both sides all are equipped with two parallel arrangement's logical groove 7, lead to groove 7 and set up respectively in the upper portion and the lower part of rectangle box 1, and every all slides rack 71 in leading to groove 7, all is equipped with a plurality of springs 72 in every logical groove 7, and the equal fixed connection of every spring 72 is between rack 71 and the lateral wall that leads to groove 7. The upper and lower cell wall that leads to groove 7 of every all is equipped with the spout, sliding connection slide 73 between two spouts, outside rectangle box 1 all can stretch out in every slide 73 one side, rack 71 and the one-to-one setting of slide 73, every rack 71 the flank of tooth all with the setting of the butt in slide 73 one side that corresponds, under the free state, spring 72 can tightly support the flank of tooth of rack 71 in slide 73 one side. The pull rod 731 is fixedly connected to one side of each sliding plate 73 extending out of the rectangular box 1, and the two handles 8 are fixedly connected to one side of the rectangular box 1 provided with the opening respectively.

During the use, the wall that will install above-mentioned electric fire automatic alarm device breaks the hole with the adaptation of rectangle box 1 volume, put into the trompil of wall with rectangle box 1 level again, after placing, the pull rod 731 of pulling slide 73, pull out rectangle box 1 along the spout one by one with slide 73 through pull rod 731 outside, under the effort of spring 72, the flank of tooth of rack 71 can stretch out logical groove 7 and tightly support the pore wall at the wall trompil, thereby make rectangle box 1 firmly fixed in the wall, in order to monitor, alarm work. When the rectangular box 1 needs to be moved out of the wall surface, the sliding plates 73 are inserted into the through grooves 7 one by one along the sliding groove direction, the sliding plates 73 are in contact with the tooth surfaces of the racks 71 in the moving process, the racks 71 are squeezed into the through grooves 7 again, and then the rectangular box 1 can be quickly moved out of the wall surface by pulling the handles 8.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
